RipBot264 Blu-ray processing, result and opinion

vbimport

#1

After reading many recommendations, last night I decided to try Ripbot264 with Iron Man Blu-ray 50GB disc converted to 8.5GB (BD9).

Loaded the main movie (00010.m2ts, size 32,659,122 KB) and RipBot264 took few minutes to demux selected streams to a temporary folder. Then next screen is Encoding settings. Set to:

  • Mode 2-Pass
  • Video Profile [level 4, 0] HD, BluRay, Consoles
  • Audio Profile 5.1 Aften AC3 640 kbps [cbr]
  • Save As Blu-ray Disc
  • Lock Size: 8150 MB

Processing 1st pass took 2 hours. Then 2nd pass = 4 hours, Total 6 hours to complete! My PC specs are Q6600 quad core, 4GB RAM, 10K Raptor, Windows XP Pro SP3. CPU usage was 100% on all 4 cores during encoding.

Playback using PowerDVD = good to very good, not excellent IMO. I can see some artifacts or pixellations

Also… PowerDVD info shows:

  • Video: MPEG-4 AVC , between 3 - 13 Mbps, mostly 7-9Mbps
  • Audio: Dolby Digital 5.1 640Kbps
  • Subtitle = missing! I forgot something? :sad:

Meanwhile, playback the Original Iran Man Blu-ray, PowerDVD shows:

  • Video: MPEG-4 AVC mostly around 28-35 Mbps, some scenes over 40 Mbps
  • Audio: Dolby TrueHD 5.1 over 3000Kbps

My opinion, while the result is a blu-ray structure but video and audio quality is no where close to the Blu-ray version, more like the DVD version, the bitrate proves it. :frowning:
Any advice to tweak the settings to get better results?

I will try burn to DVD+R DL and check out on the PS3. Also will try converting to BD 25GB and see how it goes. :iagree: :smiley:

I just tried out RipBot the other day and didn’t feel it retained BD quality neither. In fact it was no better than when I’ve been converting the BD main movie m2ts to DVD format.

I first extract the main movie m2ts from the BD rip using TSRemux (stripping unwanted audio and subtitle streams)… then I just load that m2ts into ConvertXtoDVD… and the output rivals commercial DVDs’ quality. Very, very crisp… and that’s to DVD5 single layer! It’d probably be just a bit crisper if you set it to 8.5 GBs. And ConvertX only takes around an hour to hour and a half… The Dark Knight took 2 hours but it’s a long movie.

Edit: I see that you might want to keep subtitles, then you would also need TSMuxer to demux the PGS subtitle stream to SUP file, then SUPRip to correct and convert to a .srt file… then ConvertX will see the subtitle, as long as the m2ts and the srt files are the same name and in the same folder.

There is a free trial of ConvertX so you can try and compare for yourself… only thing is that they hard-code a message into the video throughout the movie on the free trial version.

I actually got it for $29.99 (40% off) by going to [B]this site [/B] … which is actually VSO’s default pay site. Sometimes it only shows that $29.99 the first time you go to that page, going back to the regular price of $49.99 on subsequent visits to that RegNow pay site… but you can easily get past that by closing out IE and re-opening it, and then again it shows the $29.99 the first time you visit that site each time you re-open IE new.

Hmm, odd. I got excellent quality using Ripbot264 going from a full blu ray movie to a single layer dvd using H264. No artifacts or pixellation for me.

I don’t have a very large screen to test with however. On the 24" monitor it looks identical to the original.

No, no artifacts or pixelations, but it was clearly not up to BluRay quality. It didn’t look any better than using ConvertX to convert into DVD format.

It wasn’t bad at all, but considering that it takes over 6 hours, compared to 1 or 1 1/2 hours that it takes ConvertX… I had hoped to see a dramaticly better quality but it was about the same, with neither able to compare with BluRay itself. So I decided that I might as well go with the faster since I didn’t mind the $29.99 price. :slight_smile: which I had paid for already, and still would have, had I compared the two prior to purchasing ConvertX

In ripbot you can set the level for up to Level 4.1 and maintain compatibility with the majority of bluray players, which allows it to retain higher bitrates for scenes requiring additional detail - if you check wikipedia, you can check that the 4.1 profile allows significantly higher bitrates.

I am yet to see any artifacts in any ripbot 264 converted videos.

The results are nice, and significantly better than an original DVD on a large TV (aka >40").

However the difference between a real BD & the converted BD is that much of the background detail appears to be discarded.

Any conversion of a Bluray (upto 2hr) movie down to an SL disc should be converted to 720p resolution.
Any movie longer than approx 2hrs needs to be 720p on an 8GB disc.
You can maintain the audio stream as the original, if you want. AC3 sound is pretty crap. Uncompressed audio though will blow out the space required for your conversion - try ripping the standard DTS stream instead, rather than the Lossless/master quality audio stream.

I find that computer displays are generally quite bright, and anything you ever pick up on a computer will likely never be noticed on a real TV.

I use ripbot264 to really shrink some BD’s and HD-DVD’s I have down to 4.7GB. I own the originals so can rip again but the ability to use cheap DVD blanks for carrying them around is ideal so no comments on perceived quality please, it fits my needs perfectly. I usually start the transcode off over night and when I get back from work the next evening its all done, this is with a Q6600 at 333x8.

I have no problems using low bitrates (down to 3.5Mbps) for 1080p encodes when coupled to AC3 audio at the lowest 3xxkbps setting, saying this however I do tweak ffdshow to apply some slight post-processing. I do temporal de-noise by 1 notch (removes the added film noise that seems inherent on Blu-Ray titles) and also add a very very slight touch of edge sharpness.

I have yet to see any compression artifacts on my 32" 1080i TV, 40" Full HD TV or when looking closely at my 1900x1200 laptop screen. The artifacts I can see are also present on the original disc when viewed (there are a large number of really poor transfers that show BR in a very bad light, I even think a few are just upsampled DVD images).

Oh thank god it’s not just me that can see the noise!

It’s not actually inherent, it seems to just be many Bluray titles - I suspect they’re rushed through mastering to production as quickly as possible.

Casino Royale was gorgeous without the noise.

I also find that many Bluray titles have very sharp/well defined edges to many objects which just seems unnatural - or maybe I’m just used to 25yrs of blurry Standard Definition :iagree:

hi!
i still have to figure which are the settings for converting to BD 25GB…
my english is not so good, so i need someone that can tell me
exactly the steps to convert to a BD 25GB!!

someone can help me? :sad: :bigsmile:
thx!!!

@evocsilver: you can type it manually, don’t choose from the dropdown. I suggest a number around 23000 MB.


#10

Thanks zaina…I’ve been looking for a solution to that with Ripbot myself :slight_smile:


#11

Hi
I am new to this forum, but have sucsesfully converted 10 BD movies.

Yes i own them, but i have a mythtv setup and blueray is NOT supported in linux.

i use constant quality single pass (transformers took 10 hours on a quad core 2.4ghz q6600…actually i made sure i stuck with default settings and made absolutely sure that i was getting 1920x1080p.

converted these to .mp4 using the 4.1 blueray setting.

i would like to let everyone know that i am not backing these up to DVD or even dual layer dvd…when i am done backing them up depending on how long the movie is and the quality of the original disk i have files that range from 5.16gig to just under 11 gig.

using anydvd and ripbot.

i have a 1920x1200 24 inch computer monitor and also a 42 inch phillips 1080p LCD TV…so i can see before and after pixel for pixel…i cannot tell the difference at all…doesnt matter if i am comparing it on my PC or comparing my finished .mp4 file on my mythbox vs. my ps3.

i cannot tell the difference…you guys are saying that you CAN tell the difference…maybe we should all list out conversion settings including the end result format so that we can compare our results.

i am going to list the exact versions of ripbot and it’s components that are working for me (i am not upgrading since everything is working PERFECTLY!

here goes

ripbot264 version 1.11.5

avisynth version 2.5.8.4

ffdshow version 1.0.0.2417

MatroskaSplitter version 1.8.122.8

what is everyone else using?


#12

Good idea proposed above. I’m not using anything until I buy a bd rewritable to cut down on expenditure of disks. However, once the results start to appear I’ll go for the “best settings”. I would however be interested in seeing if there is a visible difference going from dvd 9 to 25gig bd?


#13

Yes there is a noticeable quality difference (if you are looking for it) … but not enough for the vast majority of people to notice the difference, nor care about, nor reduce their enjoyment of the movie. :iagree:


#14

I still can’t notice the difference…I really don’t think there is any…

BUT I am doing things differently that everyone else here.

I am not trying to fit it on a double layer DVD.

I WOULD notice the difference for example if I were to try and fit Transformers the movie onto a double layer DVD and limit myself to 8 gigs of data, but I am not and it is just over 12 gig in size…WOW a 33 percent loss right there for choosing to limit yourself to a dual layer DVD and I am not willing to take such a loss.

I am also converting to MP4 format.

What settings are you using…you said it is noticeable, but never mentioned what settings you are using, what the end result format is, and what versions of ripbot as well as its plug-ins. this COULD be the key here.

Honestly I feel the only reason I am not experiencing quality loss is because I am not limiting the output file size…I am letting the software do what it wants as regards to size…the end result in file size is simply “it is what it is”

I have a terabyte drive in my myth box so I am not concerned about file size

but comparing my 12+gig transformers encode to someone else’s 8 gig limited dual layer DVD encode…YES I’m sure that there will be a NOTICABLE difference.

I hope you can agree with this.


#15

It’s odd, jdobbs who created DVD Rebuilder and is working on a BD Rebuilder version (which the beta may be out soon) doesn’t think a BD9 looks any different then a regular BD movie:

http://forum.doom9.org/showpost.php?p=1226893&postcount=574

those guys over at doom are usually very picky … one thing he said was it took around 20 hours to process, so maybe he’s doing something different.


#16

I also converted few movies, and if you pick the correct bitrate and try to be conservative, results are good.

I never tried to re-encode BD movie to DVD level, i think that is a bit extreme.

what zaina did

Video: MPEG-4 AVC , between 3 - 13 Mbps, mostly 7-9Mbps

1080p movie at that low bitrate is simply crazy.

My suggestion to you is to try out the Beta of BD-ReBuilder and see for yourself.
I mentioned earlier in this thread how converting a BluRay movie-only m2ts file to DVD format using ConvertXtoDVD could still end up in DVD quality… but what BD-RB does in encoding a 25 GB m2ts down to a BD-9 8GB BluRay is incredible. You have to see for yourself.


#18

that BD rebuilder uses x264 encoder, so there really is nothing new or amazing about it. only difference is that it can keep the menus and all the extra junk.

almost every single third party program uses x264 for encoding h264: ripbot, automkv, meegui, encode360 etc…

same old good encoder, just new GUI on top.

But BD-RB just seems to get it done faster. Have you even tried BD-RB??.. any all the rest? How long do they take on your system? :slight_smile:


#20

Tried to find the latest link to BD rebuilder was unable. Anybody have it as I beleive a number of versions have now ensued. Thank you :slight_smile: My bad just found it. It will be interesting to see how much faster it will be?
